Apple claims it is entitled to $2.525 billion of damages in its battle against Samsung over patents for technology used in smartphones and tablets. The estimate was revealed in a court filing early Tuesday, almost a week before the companies are scheduled on July 30 to begin a jury trial before U.S. District Judge Lucy Koh in San Jose, California.

Apple accused Samsung of infringing its patents by making its popular Galaxy phone and computer tablets "work and look" like Apple products, enabling the South Korean company to overtake it as the world's largest maker of smartphones.

In its court filing, Apple said Samsung owes "substantial monetary damages" because it illegally "chose to compete by copying Apple."

It said Samsung has been "unjustly enriched" by an undisclosed amount -- presumably $2 billion -- and deprived Apple of $500 million of profit and $25 million of reasonable royalty damages. This results in "a combined total of $2.525 billion" of damages, Apple said.

Right after Apple's filing, Samsung countered with a filing accusing the California-based company of trying "to stifle legitimate competition and limit consumer choice to maintain its historically exorbitant profits."
